Book Description
Ultrafast time-resolved infrared spectroscopy provides a powerful tool for studying the photochemistry of organometallic complexes. The studies described herein focus on the mechanisms of photochemically initiated organometallic reactions with a particular emphasis on two topics: the role of spin states and spin state changes in organometallic reactions, and the primary photochemical dynamics of complexes containing metal-metal bonds (e.g. transition metal dimers and clusters). Many of these studies seek to uncover trends in reactivity based on the spin states of organometallic reaction intermediates, with the goal of being able to offer some level of predictive insight into the reactivity of complexes as classified by their spin multiplicity. The reactivity of various coordinatively unsaturated reaction intermediates are studied with respect to bond activation, electron transfer, excited state photoisomerization, and other classes of reactions important to organometallic catalysis. A second focus, which shares some degree of overlap with the topic of spin state changes, is the primary photochemistry of complexes containing metal-metal bonds. Several of the studies reported herein use time-resolved infrared spectroscopy to examine the primary photochemical processes occurring upon excitation of transition metal dimers and clusters, and often spin state changes also found to play an important role. Results of computational chemistry calculations are frequently used to facilitate interpretation of the experimental results by computation of structures, relative energies, infrared spectra, and spin-orbit coupling for the complexes studied experimentally. Additional studies outside these two primary areas of focus also investigated the ring-slippage of cyclopentadienyl ligands and the CO-delivery properties of a popular CO-Releasing Molecule.
Reviews of Reactive Intermediate Chemistry

Category : Science
Languages : en
Pages : 492
Book Description
The chemistry of reactive intermediates is central to a modern mechanistic and quantitative understanding of organic chemistry. Moreover, it underlies a significant portion of modern synthetic chemistry and is integral to a molecular view of biological chemistry. Reviews in Reactive Intermediate Chemistry presents an up-to-date, authoritative guide to this fundamental topic. Although it follows Reactive Intermediate Chemistry by the same authors, it serves as a free-standing resource for the entire chemical and biochemical community. The book includes: Relevant, practical applications Coverage of such topics as mass spectrometry methods, reactive intermediates in interstellar medium, quantum mechanical tunnelling, solvent effects, reactive intermediates in biochemical processes, and excited state surfaces Discussions of emerging areas, particularly those involving dynamics and theories Concluding sections identifying key directions for future research are provided at the end of each chapter
Photoprocesses in Transition Metal Complexes, Biosystems and Other Molecules. Experiment and Theory
Author: E. KochanskiPublisher: Springer Science & Business Media
ISBN: 9401126984
Category : Science
Languages : en
Pages : 448
Book Description
The scope of this paper is to recall fundamental notions of the molecular spectroscopy and dynamics, necessary for discussion of photophysical and photochemical processes in condensed phases. We will thus treat in a more detailed way the specific features which are important for molecular systems strongly interacting with their environment. Other aspects such as the time evolution of isolated molecules, single-level excitation and state-to-state chemistry, important for the gas-phase photophysics are omitted. We start (Sec.2) with a brief description of radiative processes (light absorption and emission) in molecules. In the quantum-mechanical treatment of this problem, the appropriate basis is that of so-called zero-order states, corresponding to the traditional scheme of electronic states (singlets, doublets, triplets etc.) and vibrational levels belonging to each state. The important point will be deduction of selection rules for most radiative transitions. At this stage all molecular states are considered as stationary states. In order to treat the breakdown of simple selection rules and non-radiative transitions between individual molecular states, it is necessary to take into account the mechanisms coupling the zero-order states (Sec.3). We will first focus on intramolecular coupling effects and then discuss the solvent effects on intramolecular relaxation processes. The problem of the non-radiative transfer of the electronic energy between different molecules - closely related to that of the energy dissipation within a single molecule will be treated in Sec.4.

Pages : 366
Book Description
This book is devoted to the broad subject of flavor physics, embracing the question of what distinguishes one type of elementary particles from another. The articles range from the forefront of formal theory (treating the physics of extra dimensions) to details of particle detectors. Although special emphasis is placed on the physics of kaons, charmed and beauty particles, top quarks, and neutrinos, the articles also dealing with electroweak physics, quantum chromodynamics, supersymmetry, and dynamical electroweak symmetry breaking. Violations of fundamental symmetries such as time reversal invariance are discussed in the context of neutral kaons, beauty particles, electric dipole moments, and parity violation in atoms. The physics of the Cabibbo-Kobayashi-Maskawa matrix and of quark masses are described in some detail, both from the standpoint of present and future experimental knowledge and from a more fundamental viewpoint, where physicists are still searching for the correct theory
